- Comment on Could one legally get a hold of those bank bill dye security dye packs, dye your own legally obtained cash with it, and spend it places? Just to make people suspect you're secretly a bank robber. 3 days ago:
Not true- ATMs definitely track SN, that’s how they catch theives. I’m almost certain banks would record SN too, at least nowadays. It would be stupid simple.

Okay, so conversion or unjust enrichment instead of literal theft.

- Comment on Realized 99% of all my chargers are USB-C. This can only mean one thing. New USB bout to drop! 3 weeks ago:
Pin pitch means how tiny the physical pins in the connector can be spaced apart.
IR drop losses happen because a wire has resistance, it isn’t a perfect conductor. 28AWG wire has about 0.22ohm/m. Given a 2 meter cable, you might expect to see 0.44ohm one-way. Current is also travelling back, so the circuit “sees” another 0.44ohm. That’s a total of 0.88ohm
A wire will cause voltage drop following ohm’s law. V=I/*R. So for 1A of current, you will see 0.88V lost.
Say you’re trying to charge at 15W (5V 3A), your phone is only going to ‘see’ 2.36 volts, and 7.9W are wasted in the cable.
For a 100W device (20V, 5A), 4.4V are lost, also meaning 22W are wasted.

The concentration of them is rising exponentially, that’s the part that terrifies me.
It’s possible we just haven’t crossed a threshold yet.

- Comment on The plan for nationwide fiber internet might be upended for Starlink 2 months ago:
Microwave point-to-point radios are fastest because they travel through air, but more importantly, are typically the shortest path possible by line-of-sight.
Being 66.7% of speed of light doesn’t matter terribly when you consider that the cable path is shorter by more than 66.7% of path taken by satelite link.
There’s also the idea of

- Comment on Does anyone have any advice on how to make homemade conductive paint to fix a. cracked carbon trace in a game controller? 3 months ago:
You’ll have a bad time with used copper tape. Just like why it isn’t advised to reuse any other kind of tape (duct, packaging, electrical)

Radio waves are a specific wavelength/band of the EM spectrum. Light is not radio waves, just as radiowaves aren’t light.
They’re both electromagnetic waves.

2mA minimum, and that’s just q current. It’s gonna be much higher when you’re actually using it for a clock.
I’m sure the casio’s main power sink is the display. I bet the refresh rate could be reduced for better battery life.
- Comment on If we silenced all the sources of misinformation/disinformation people would be agast at how quiet it is. 3 months ago:
Science has an unintuitive philosophical system, it is actually impossible (or just not feasible) to “disprove” a lot of things absolutely 100%.
Best you can do is prove something, or fail to prove something.
And it does make some sense, there’s uncertainty in measurements, there’s some probability and statistics involved.
Proving there are NOT aliens out there would require checking every inch of every planet for life, remains, or fossils.

People also don’t realize how incredibly stupid humans can be. I don’t mean that in a judgemental or moral kind of way, I mean that the educational system has failed a lot of people.
There’s some % of people that could use AI for every decision in their lives and the outcome would be the same or better.
That’s even more terrifying IMO.
